No es necesario retrasar la asignaci\u00f3n del mapa sparse_ext hasta que se configure la matriz bvecs, as\u00ed que solucione esto moviendo la asignaci\u00f3n de sparse_ext un poco antes. Adem\u00e1s, haga un ajuste similar en __ceph_sync_read() para lograr coherencia (una p\u00e9rdida del mismo tipo en __ceph_sync_read() se ha abordado de forma diferente)."
